To realize all-ceramic restorations applied with zirconia, it is important of development of surface modification method for zirconia in order to improve the bonding strength to veneering porcelains, the bonding strength to cements, and biocompatibility. Bonding strength of zirconia with surface treatment such as sandblasting, acid etching, silane coupling, hydrothermal treatment, and glass coating were determined to the veneering porcelains and resin cements, and their biocompatibility were evaluated. The results demonstrated that zirconia showed different behavior from those of conventional dental ceramics. It indicates that new surface treatment method specialized to zirconia should be developed.

为了实现氧化锆全瓷修复体的应用，开发氧化锆的表面改性方法以提高与贴面瓷的粘结强度、与骨水泥的粘结强度以及生物相容性非常重要。测定了经过喷砂、酸蚀、硅烷偶联、水热处理、玻璃涂层等表面处理的氧化锆与贴面瓷和树脂水门汀的结合强度，并评价了它们的生物相容性。结果表明，氧化锆表现出与传统牙科陶瓷不同的行为。这表明应开发专门针对氧化锆的新型表面处理方法。
